first off, there is no way I would spend that much on a kitfox. now between my two airplanes, well I still don't have that much in the two. I have a kitfox 4 and a rv7a. both have a mighty fine engine. won't go into that but, I think you got the salesmans top prize. yes every manufacturer out there has their top model. do you need it? I couldn't tell you. that's up to what YOU want. Both my airplanes are basic on panels. Engines, that a different story. I do have the uls in my kitfox with in flight adjustable prop, I have 27.5 tires and a T3 with 8inch wide in the back. much more than that for other things. total investment over the years is well below 50 K . everything is what it is, yes there is the best of the best, do you need it, can't tell you. there is always a compromise. are you building or wanting something to blow everybody else away or are you wanting something to give you the ah ha moment.
